Diverse well describes the myriad digital modulation schemes used in modern voice and data communications. The alphabet soup of terminology extends well beyond the familiar QAM and GMSK fundamentals ...

Palo Alto, Calif.—Test-and-measurement supplier Agilent Technologies Inc. is rolling out a combination of products that tightly integrate digital signal capture of Agilent's logic analyzers with the ...

Testing transceiver and converter interfaces requires orthogonal in-phase and quadrature (IQ) analog signals; that is, the phase relationship of the two must be very close to a 90-degree phase offset, ...

Vector modulation is increasingly used in microwave and satellite communication applications, but generating vector-modulated signals for measurement can be difficult and expensive. However, using ...
